My six month old Welsummer/Production Red mix was laying beautiful dark brown eggs nearly every day up until earlier this week. She's acting completely normal, looks healthy, and it's too young to start molting, so I'm beginning to get worried. We found a mouse in the coop this afternoon, but it's the first time I've seen one around here besides one my dog killed earlier this year (before the chicken came to stay). Could this somehow be related?
